Background technique

Generally, when there is a service that needs to send downlink data to a terminal in an idle state, the network sends a paging message to the terminal, so that the terminal knows that the network needs the terminal to enter the connected state to receive data.

The supported network slicing service does not match the network slicing service required by the terminal, which will cause some communication services of the terminal, such as vertical industry services, to be unable to be carried out, which has a huge impact on the terminal performance and needs to be optimized.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is used to describe the association relationship of associated objects, for example, it means that there can be three relationships between the associated objects before and after, for example, A and/or B can mean: A alone exists, A and B exist simultaneously, There are three cases of B alone. The character "/" in this document generally indicates that the related objects are "or".

In order to clearly illustrate the idea of the embodiments of the present application, firstly, a brief description is given of a related processing process of a terminal device accessing a network in a communication system.

In the art, when there is a service that needs to send downlink data to a terminal in an idle state or in an inactive state, the network first sends paging information to the terminal, so that the terminal knows that the network needs the terminal to enter the connected state to receive data. The process is roughly as follows:

1. The terminal attempts to receive a paging message from the network at a fixed time point in the wake-up phase in each discontinuous reception period.

2. When the terminal detects the DCI indication information on the PDCCH, it will know that the network may have a paging message sent to itself.

3. The terminal decodes the paging message on the PDSCH according to the indication of the time-frequency resource allocation information given in the DCI indication information.

4. After receiving the paging message:

a) For the terminal in the idle state: check whether the "pagingRecord IE" contains the terminal identifier "ue-Identity" which is the same as its own identity ID. If so, the terminal sends the information of the "ue-Identity" and the possible access type "accessType" to the upper layer, and the higher layer instructs the MAC layer to perform the random access procedure.

b) For a terminal in an inactive inactive state: check whether the "pagingRecord IE" contains the same "ue-Identity" as the "full-RNTI" stored by itself. If so, the terminal performs the connection recovery process.

Regarding message 3 (msg3): RRCSetupRequest in the random access process, for a terminal in an idle state, the RRCSetupRequest sent in the contention-based random access carries its own ID. If the MAC PDU of msg4 received later contains a UE conflict resolution ID that matches the CCCH SDU sent by the terminal in msg3, the terminal wins the competition and the random access succeeds.

Regarding the msg3:RRCResumeRequest in the random access process, for the terminal in the inactive state, the purpose of sending the RRCResumeRequest is to request the network to resume the suspended RRC connection. If the subsequently received MAC PDU containing msg4:RRCResume contains a UE conflict resolution ID that matches the CCCH SDU sent by the terminal in msg3, the terminal wins the competition, the random access succeeds, and the terminal resumes the connected state.

If the base station gNB refuses to establish an RRC connection for the UE, it sends an RRC rejection message through the DL CCCH. The RRC rejection message carries a timer, and the terminal is not allowed to access the cell until the timer expires.

The terminal sends an uplink NAS message to the core network through the RRCSetupComplete signaling to inform the terminal of the purpose of establishing a connection, such as attach or detach. The terminal also reports the required network slice information to the base station, so that the base station can coordinate with the core network to establish an appropriate PDU session tunnel.

The terminal sends an uplink NAS message to the core network through the RRCResumeComplete signaling, informing the core network of the purpose of restoring the connection of the terminal.

However, for a terminal that enters the connected state through the random access process, if the accessed cell cannot provide the required network slicing service for the terminal, or the network slicing service supported by the cell does not match the network slicing service required by the terminal, it will lead to The terminal service cannot be carried out normally, and according to the aforementioned access process, it does not consider how the network slicing service currently supported by the cell does not meet the terminal requirements, cannot quickly access other suitable cells, and cannot provide services to users in time. It can be seen that after the current terminal enters the connected state, when there is a data service, the terminal cannot reconnect to the cell that matches the network slice required by the service in time.

To this end, an embodiment of the present application provides an information processing method, which is applied to a terminal device. Referring to FIG. 2 , the method includes:

S101: The terminal device processes the first network slice identification information and/or the identification information of the terminal device to perform an access process.

According to the embodiments of the present application, during the access process of the terminal device, the terminal device may perform the access process according to the identification information of the terminal device, and may also perform the access based on the processing of the network slice identification information. Considering that the terminal device does not always need to complete the access according to, for example, the communication quality or signal strength, the network slice information will also affect the access process, which can improve the performance of the terminal device to a certain extent.

Correspondingly, an embodiment of the present application further provides an information processing method, which is applied to a network device. Referring to FIG. 3 , the method includes:

S201: The network device processes the identification information of the first network slice and/or the identification information of the terminal device, so that the terminal device performs an access process.

The network device in the embodiments of the present application can determine its own behavior by processing the network slice identification information and/or the identification information of the terminal device, so that the terminal device can access the cell that meets the requirements of the network slice service, so as to improve the performance of the terminal device and the system. for overall performance purposes.

The downlink process and the uplink process of the embodiments of the present application are respectively described in detail below, thereby describing various implementation manners of the embodiments of the present application.

Case 1: The first network slice identification information corresponds to the network slice where the downlink data of the terminal device is located

In the embodiment of the present application, optionally, the terminal device processing the identification information of the first network slice and the identification information of the terminal device includes: receiving, by the terminal device, a paging message sent by the network device, The paging message includes the identification information of the terminal device and the identification information of the first network slice.

Optionally, the terminal device performs an access procedure oriented to the first cell, and sends the identification information of the terminal device or the identification information of the first network slice to the network device.

Optionally, if the terminal device receives predetermined type information, the terminal device performs cell handover or cell reselection according to the predetermined type information.

According to the embodiments of the present application, in a relevant application scenario, for example, the core network starts the paging process when there is downlink service data that needs to be sent to the terminal device, and the paging message can carry the relevant information of the slice to which the service transmission belongs. For example, slice ID, in this way, the slice identification information corresponding to the downlink service data can be notified to the network device. According to this, the network device can send a paging message to the terminal device, and carry the identity information and slice identification information of the terminal device in the paging message to the terminal device, so that the terminal device can know that there is downlink data to be received on the corresponding slice, which requires the terminal device The device is connected to the network.

The terminal device performs the access procedure, and sends its own identification, such as the UE ID, to the network, or sends the slice information carried in the paging message, such as the slice ID, to the network, as an explicit indication information. Here, for example, since the paging message of the network device includes the UE ID and the slice ID, the terminal can notify the network of the slice attribute information required by the service data by sending one of the two.

The network device may determine whether to complete the access process of the terminal device to the current cell according to whether the slice attribute supported by the current cell (for example, the first cell) matches the slice attribute required by the terminal device, wherein, if the two slice attributes If it does not match, it means that the current cell cannot support data transmission on the slice, and the terminal device should not access the current cell, then the network device sends a predetermined message to the terminal device, so that the terminal device no longer accesses the current cell, but reconnects to other A suitable cell (for example, referred to as a second cell) may be a cell with matching slice attributes.

In this way, according to the embodiment of the present application, after the terminal device enters the connected state, if the cell slicing resources do not meet the requirements, the terminal device can quickly access the cell with suitable slicing resources, avoiding the slicing service of the access cell and its own If the required slice service does not match, the terminal service cannot be carried out, and the terminal device can provide services to the user after quickly accessing other suitable cells. Therefore, the overall performance of the terminal device can be improved to a certain extent by using the embodiments of the present application.

Correspondingly, in the embodiment of the present application, optionally, the network device processing the identification information of the first network slice and the identification information of the terminal device includes: the network device sends a paging message to the terminal device , the paging message includes the identification information of the terminal device and the identification information of the first network slice, and the paging message is used for the terminal device to perform an access procedure.

Optionally, the network device receives the identification information of the terminal device or the identification information of the first network slice sent by the terminal device.

Optionally, if the first network slice identification information does not match the network slice service supported by the network device, the network device sends predetermined type information to the terminal device, and the predetermined type information is used for the terminal. The device performs cell handover or cell reselection.

Using the embodiment of the present application, the network device can judge whether the access process of the terminal device to the current cell is completed according to whether the slice attribute supported by the current cell matches the slice attribute required by the terminal device. If the two slice attributes do not match, the network The device sends a predetermined message to the terminal device, and the terminal device can quickly access the cell with suitable slicing resources, avoiding that the slicing service of the access cell does not match the slicing service it needs, and the terminal service cannot be carried out and the overall performance of the system is dragged down.

In the embodiment of the present application, as described above, the terminal device may send its own identity information such as UE ID, or the first network slice identification information such as slice ID to the network device during the access process.

Specifically, the relevant information may be carried in the third step message msg3 or the fifth step message msg5 of the access procedure.

Optionally, the identity information of the terminal device is included in msg3, for example, the UE ID is carried in msg3.

Optionally, msg5 includes the first network slice identification information, for example, the slice ID is carried in msg5.

More specifically, optionally, the msg3 may include at least one of the following signaling: setup request RRCSetupRequest signaling, recovery request RRCResumeRequest signaling, and reconnection request RRCRe-establishmentRequest signaling. The UE ID may be carried through one or more of these signaling.

Optionally, the msg5 may include at least one of the following signaling: setup complete RRCSetupCompletet signaling, recovery complete RRCResumeComplete signaling, and reconnect complete RRCRe-establishmentComplete signaling. The slice ID can be carried through one or more of these signaling.

Correspondingly, the network device may determine the network slice information required by the terminal device according to the UE ID in msg3 or the slice ID in msg5. The following describes in detail through several specific examples.

For example, the paging message sent by the network device carries the UE ID and information about network slices required for service data transmission, such as slice ID. For the terminal device in the idle state, after receiving the paging message, compare the UE ID in it with its own UE ID If it matches, the access procedure is started, and the UE ID of the self is carried in the third step message msg3, for example, it can be carried in the RRCSetupRequest.

Correspondingly, the network device receives msg3, wherein the RRCSetupRequest contains UE ID information, and the UE ID can be at least one of the following:

a) ng-5G-S-TMSI-Part1 (the rightmost 39 bits of ng-5G-STMSI),

b) ShortI-RNTI-Value (24-bit ID),

c) RNTI-Value (40-bit ID),

The network device can use the UE ID carried in the paging message and the slice ID of the network slice required for service data transmission as the received slice ID of the network slice service required by the UE.

For another example, the paging message sent by the network device carries the UE ID and information about network slices required for service data transmission, such as the slice ID. For the terminal device in the idle state, after receiving the paging message, compare the UE ID in it with its own UE. If the ID matches, the access process starts, and the slice ID obtained through the paging message is carried in the fifth step message msg5, for example, it can be carried in RRCSetupComplete.

Correspondingly, the network device receives the slice ID of the first network slice in the RRCSetupComplete of msg5, that is, the network device knows the slice ID of the network slice service required by the UE.

For another example, the paging message sent by the network device carries the UE ID and information about network slices required for service data transmission, such as the slice ID. For the terminal device in the inactive state, after receiving the paging message, compare the UE ID in it with its own. If the UE ID matches, the RRC connection recovery process starts, and the slice ID obtained through the paging message is carried in the fifth step message msg5, for example, it can be carried in RRCResumeComplete.

Correspondingly, the network device receives the slice ID of the first network slice in the RRCResumeComplete of msg5, that is, the network device knows the slice ID of the network slice service required by the UE.

Further, optionally, the msg5 may further include the existing neighbor cell measurement information of the terminal device, for example, the msg5 carries the existing neighbor cell measurement information of the terminal device. Correspondingly, the network device can help the terminal device select or reselect a cell that meets the current required network slice service according to the neighbor cell measurement information in msg5, and the terminal device can re-initiate the access process to the conforming cell to achieve fast handover.

The above-described embodiments can be understood as a way of explicitly notifying network slice identification information.

The embodiment of the present application may also adopt an implicit notification method, for example, the terminal device may apply the random access resource corresponding to the first network slice to perform a random access procedure for the first cell. Correspondingly, the network device may determine the network slice required by the terminal device according to the random access resource used by the terminal device.

Wherein, optionally, the random access resource may include a random access preamble and/or a random access time-frequency position. Optionally, the indication information may be carried in a broadcast message or radio resource control RRC information sent by the network device.

In this way, the network device in the embodiment of the present application can determine the information of the network slice required by the terminal device, so as to determine whether the network slice service supported by the current cell is consistent with the network slice service required by the terminal device.

Case 2: The first network slice identification information corresponds to the network slice where the uplink data of the terminal device is located

In the embodiment of the present application, optionally, the terminal device processing the identification information of the first network slice and the identification information of the terminal device includes: performing, by the terminal device, an access procedure oriented to the first cell , sending the identification information of the terminal device and the identification information of the first network slice to the network device.

Optionally, the third step message msg3 includes the identification information of the terminal device and the identification information of the first network slice.

Optionally, the message msg5 in the fifth step includes the identification information of the terminal device and the identification information of the first network slice.

Correspondingly, the network device can receive the identity information of the terminal device and the first network slice identification information sent by the terminal device, for example, can obtain the UE ID and slice ID carried in msg3, and can also obtain UE ID and slice ID carried in msg5.

It can be seen that, unlike the downlink process described in Case 1, in the uplink process, the terminal device needs to report both the UE ID and the slice ID to the network device, so that the network device can determine the network supported by the current cell according to the received slice ID. Whether the slicing service is compatible with the network slicing service required by the terminal device.

Here, other information in the uplink process may be consistent with the information given in the foregoing "Case 1", such as the possible signaling forms of msg3 and msg5, and msg5 may also include idle state or inactive state terminal equipment measurement The adjacent cell measurement information, etc., are omitted here.

Based on the various embodiments described above, for the access process triggered by the downlink paging message sent by the network device, or the access process triggered by the uplink service data demand of the terminal device itself, the network device can know the information of the terminal device. The required identification information slice ID of the first network slice service.

Then, if the first network slice identification information does not match the network slice service supported by the network device, the network device in this embodiment of the present application may send predetermined type information to the terminal device, where the predetermined type information is used for all network slice services. The terminal equipment performs cell handover or cell reselection, that is, performs fast cell handover or cell reselection.

Correspondingly, if the terminal device receives predetermined type information, the terminal device performs cell handover or cell reselection according to the predetermined type information.

In different embodiments of the present application, the predetermined type of information may be different, which will be described separately below.

Optionally, the predetermined type information includes a rejection message, and the rejection message includes information indicating that the required network slice service is not supported.

Wherein, optionally, the rejection message may further include redirection information and/or reselection priority information.

Specifically, first, the rejection message may include reasons for rejecting terminal access, such as rejection reason information such as not supporting required network slice services, network slice mismatch, and the like. Secondly, the rejection message may further include redirection information and/or reselection priority information. After receiving the RRCReject signaling with the rejection reason "currently required network slicing service not supported", the terminal immediately starts the cell selection/reselection process, selects/reselects to a cell that meets the current required network slicing service, and re-initiates access. Optionally, the access cell is selected according to the redirection and/or reselection priority information given in the RRC signaling. Optionally, the redirection information includes cell ID related information. The UE can re-determine a cell suitable for network slicing resources based on this, initiate an access procedure, and complete fast access.

Optionally, the predetermined type information includes a release message, and the release message includes at least one of the following information: redirection information, reselection priority information, and de-prioritization request information. The UE can re-determine a cell suitable for network slicing resources based on this, initiate an access procedure, and complete fast access.

Optionally, the predetermined type of information includes a reconfiguration message, and the reconfiguration message includes at least one of the following information: a radio link layer control protocol RLC bearer addition modification list, an RLC bearer release list, configuration information of the target cell, The radio network temporary identifier RNTI value and dedicated random access configuration information configured by the target cell. The UE can re-determine a cell suitable for network slicing resources based on this, initiate an access procedure, and complete fast access.

Wherein, optionally, the redirection information includes frequency point information corresponding to the second cell or identification ID information of the second cell. The frequency corresponding to the second cell in the reselection priority information is the highest priority. The de-prioritization request information is used to indicate whether the current frequency or radio access technology RAT will be de-prioritized.

Using at least one of the above embodiments of the present application, the network device can determine whether to complete the access process of the terminal device to the current cell according to whether the slice attribute supported by the current cell matches the slice attribute required by the terminal device. If there is no match, the network device sends a predetermined message to the terminal device, and the terminal device can quickly access the cell with suitable slicing resources, avoiding the inability of the terminal service to be carried out due to the inconsistency between the slicing service of the access cell and the required slicing service and dragging down the system. overall performance.

The following describes a possible specific implementation process of the embodiments of the present application by using a plurality of specific examples.

Example 1

Referring to FIG. 4 , in this embodiment, the UE ID of the terminal device is 5, and the terminal receives the paging information sent by the network, wherein the content of a pagingRecord contained in the pagingRecordlist is {UE ID=5, slice ID=7}. The terminal compares the UE ID in the pagingRecord with its own UE ID, and knows that the network has a network slice where the downlink data with slice ID of 7 needs to be sent to the terminal, and the terminal needs to access the network. The terminal performs random access, and the msg3 RRCSetupRequest carries UE ID=5.

After the network receives msg3, it compares the paging information stored by itself, and learns that the purpose of the terminal accessing the network is to receive downlink data of the network slice with network slice ID=7, and it cannot support data transmission on this network slice. The network sends msg4RRCSetupReject to the terminal, which contains information such as the frequency point and/or the physical cell identity (Physical Cell Identity, PCI) ID of the cell redirected to the cell that can support network slice data transmission with slice ID=7, such as Cell 2 , the terminal initiates random access to Cell 2 to access the network.

Example 2

Referring to FIG. 5 , in this embodiment, the UE ID of the terminal device is 5, and the terminal receives the paging information sent by the network, wherein the content of a pagingRecord contained in the pagingRecordlist is {UE ID=5, slice ID=7}. The terminal compares the UE ID in the pagingRecord with its own UE ID, and knows that the network has downlink data whose network slice is 7 and needs to be sent to the terminal, and the terminal needs to access the network.
